Linear Discriminant Analysis project data on sum of eigenvectors
I know in Linear Discriminant Analysis (LDA) we project the data on a specific eigenvector or a matrix of eigenvectors to reduce the dimensionality of the data and separate classes. But what happens if we project the data on some vector V that is the sum of a couple of the eigenvectors, or the sum of 1 eigenvector and some random vector? Will that be useful?
